Abstract
To accurately perform the coupled simulation of temperature field
and stress field of complex parts and porous structures under the optimal
manufacturing process parameters, three kinds of porous structures with
different complexity were designed in this paper. Firstly, ANSYS additive
software was used to conduct the stress/deformation simulation of the whole
structure under different scanning strategies. Secondly, the optimal scanning
strategy for different porous structures was determined, then the experimental preparation was performed, and mechanical properties of compression
were tested and studied. The results show that the elastic modulus and
yield strength increase with the increase of pole diameter/wall thickness.
In addition, the quasi-static compression simulation of different structures
was performed, and the compression performance was analyzed based on
the experimental data. Finally, the stress concentration region of different
structures was obtained.
